A git pre-commit hook to do SVN style $Date$ substitution

August 10, 2016, 4:29 pm

Put the following in .git/pre-commit (make sure it’s executable):

1
git diff --cached --name-only > commits_list

And the following in .git/post-commit:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
#!/bin/bash
 
if [ -f commits_list ]
then
  currentdate=`date`
 
  cat commits_list | while read F
  do
   echo $PWD/$F
   filebase=`basename $F`
   sed -i -e 's/\$Date[^$]*\$/\$Date '"$currentdate"'\$/' $PWD/$F
   sed -i -e 's/\$Filename[^$]*\$/\$Filename '"$filebase"'\$/' $PWD/$F
   git add $PWD/$F
  done
 
  rm commits_list
  git commit --amend --no-verify -C HEAD
 
fi

Still not extensively tested…
